IMPROVEMENT IN cuLTlvAToRs.

Specification forming part of Letters Patent N0. 102,84l, dated May 10, 1870.

y To all whom it may concern.'

Be it known that I, TRUMAN MABBETT, Sr., of Vineland, in the county of Cumberland and State of New Jersey, have invented a new and useful Improvement in Gultivators; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, and to the letters of reference lnarked thereon.

My invention consists in the use and application, in cultivators, of a cutting-bar knife or skimmer, which is applied transversely at the rear end of the same, for the purpose hereinafter shown and described.

A is a cultivator ofthe pattern ordinarily in use. To the rear of it, behind the tines or teeth a, a cutting-bar or skimmer, B, is suspended by the pendants c c, which are formed in this instance with square shoulders and secured to 4the frame by means of screws and nuts. The

front edge, d, of the cutting-bar or skimmer forms a knifeedge, and takes under the soil at the same depth as the tines a, but by suitable mechanism its depth otl penetration can be made to vary and be regulated with the greatest nicety.

My invention is for the purpose of following the tines or teeth, cutting and loosening all roots, and cleaning away Weeds and rubbish.

ing again when not'eectually eradicated. It

can be manufactured of various sizes, adapted to the various kinds of plants, systems of husbandry, and to the description of land on which it is to be employed.

What l claim as my invention, and desire t0 secure by Letters Patent', is.- t

The combination with a cultivator, of an adjustable cutting-bar or skimmer B, substantially for the purpose shown and described.
